ABSTRACT The breeding goal of the Swedish Warmblood horse (SWB) is to produce internationally competitive horses in dressage and show jumping. In the current genetic evaluation, breeding values are estimated in multiple‐trait animal models where competition performance is the target trait and results from two different young horse tests serve as indicator traits. However, preselection of horses, both for young horse tests and for competitions, is not considered in the current evaluation. The overall aim of this study was to analyse the all‐or‐none trait start status, in competition and in young horse tests, for possible use in the genetic evaluation for SWB. All starts in young horse tests have been recorded since long (1973), whereas start status in competition is known from the year 2007 and onwards. Therefore, the studied population was restricted to SWB horses born between 2003 and 2018 that had the possibility to compete during the period from 2007 until 2022. Horses were categorised into four disciplines according to their sire's and grandsire's discipline categories, and only horses in the two major categories, dressage and jumping, were included in this st
